Hello guys so me and my SO been on and off since 2017.

I’m 25 and he’s 24 we’ve started dating March 2017 ,we met through a mutual contact. We had a child but she passed away. We would fight over the death of our daughter ect. He’s dated another woman right after my pregnancy lost even cheated during , I would get into fights with his friends ..they would text me harassing things . Oh by the way he’s a marine . We broken up ,I’ve seen other ppl so has he . Fast forward, we decided to get back together then (still in the marines ) I noticed we had some distance showing , I go on his Facebook to just check ,I noticed his likes turned into Hearts. I go look at the page that’s sending out these spacial reactions it’s his besf so I’m like okay let me check more cause Wtfk ish doing all this for .i then go to her page to notice her sharing a status thats captioned“he’s out fighting for our country ,” then I knew she was talking about my man tfk ..so I inboxed her ..we had it out like,she brung up my baby’s death ...we had it out on social media. Now fast forward things .they stopped seeing each other ..ect . I’ve visited out of state for family and work which he lives in that state ..we’ve hooked up and decided to get things back on track ..(I don’t think his mom is fond of me ) his mom begs so much I’m sorry but she beg a lot. Now today he’s out of the military ,gotten his own house ect ..his mom ,brother ,sister and her son lives with him ..he doesn’t have a room in his own house ,his mom complains so much about things and she doesn’t pay a dime for things. Now we’re together but thing is I don’t have the same feelings fir him like that anymore ,like he’s gotten things together..that’s so perfect and all but maybe it’s too late , just maybe too late .is it ?
